annoying kid on the bus

A little kid walks into a city bus and sits right behind the driver and starts yelling, ''If my dad was a bull and my mom a cow I'd be a little bull.''
The driver starts getting mad at the noisy kid, who continues with, ''If my dad was an elephant and my mom a girl elephant I would be a little elephant.''

The kid goes on with several animals until the bus driver gets angry and yells at the kid, ''What if your dad was gay and your mom was a prostitute?!''
